Abstract

PURPOSE:To make it possible to simply confirm the abrasion loss of a brake lining without a measuring instrument by forming a groove having a depth corresponding to a fixed abrasion loss on the sliding surface of the brake lining or forming the brake lining of a layer having different color up to the fixed abrasion loss. CONSTITUTION:When the operation of a motor is in stoppage, a brake lining 11 slides on a F bracket 4 and both the faces of a movable core 5 to obtain braking force for restricting a motor shaft 3 through a brake hub 2. A groove 11b is formed on the sliding face of the brake lining 11, and the wear state of the sliding face can be found out by observing the variation of the depth of the groove 11b with the eye, or the sliding face is formed of a different colored layer 14b up to a depth corresponding to a fixed wear quantity, for instance a wera limit, and the wear state of the sliding face can be found out by observing the variation of the depth of the different colored layer 14b with the eye.
